Definitions
- the present invention relates to an enhanced heat exchanger apparatus .
- the present invention relates also to a heat exchanger formed by several such enhanced heat exchanger apparatuses. It relates further to a method of improving a heat transfer.
- a particular application of the invention is the introduction of several enhanced heat exchanger apparatuses inside the radiant coil of a steam cxacking furnace .
- the three modes of heat transfer are conduction, convection and radiation.
- the heat transfer rate is a function of the heat surface, the heat transfer coefficient and the temperature difference between the tube wall and the fluid to be heated (cooled) .
- technical solutions to improve the heat transfer are the use of finned tubes to increase the heat transfer surface or working in a wall developed turbulent fluid flow regime.
- heat exchangers operating at high temperature, for example > 400°C
- radiant coil of the process furnaces for the steam cracking of the hydrocarbons where the tube wall temperature may reach a value as high as 1150°C or even more
- High selectivity means to increase the percentage of the more valuable products such as ethylene, propylene, butadiene at the expense of less valuable products (methane, fuel oil, etc.).
- High selectivity is achieved if the residence time is low and the temperature of the process gas is high enough to have a good conversion of the feed.
- the above goals are achieved by increasing the heat flux (by consequence, the temperature of the metal reaches a value close to its metallurgical constraint) .
- a higher temperature of the metal leads to undesired events : High rates of deposit of coke, creep and carburization .
- the technology is oriented towards the improvement of the heat transfer coefficient using tubes with inside fins of various shapes (transverse, longitudinal, or with particular angles) .
- the heat transfer can be considerably enhanced by the third mechanism: the radiative heat transfer.
- the radiative heat transfer plays an important role because it is proportional to the fourth power of the absolute temperature of the body. This is known as the Stefan- BoIzmann law.
- the exchange of energy between two surfaces of different temperatures is proportional to the difference of the fourth power of ttie absolute temperatures of the two bodies .
- the temperature of the metal is in the range of 900°C and 1175°C, while the temperature of process gas falls between 600°C and 900°C.
- An object of the present invention is to provide a heat exchanger apparatus able to increase the convective heat transfer coefficient, the heat exchange area and, above all, the heat transfer rate due to the contribution of the radiative mechanism.
- a further object of the present invention is to provide a enhanced heat exchanger apparatus to be used in all kinds of furnaces, but in particular, in the ethylene cracking furnaces. Still a further object is to provide a method to improve the heat transfer rate .
- the advantage of the use of the enhanced radiant heat exchanger (ERHE) apparatus according to the present invention is that it allows an ethylene cracking furnace to dramatically increase the heat exchange / while keeping the tube wall temperature on the external tube low. Besides the longer run length of the furnace, due to the reduced coking rate, a higher selectivity (i.e. higher ethylene and propylene yields compared with bare tubes) can be expected. Maintenance costs will be also reduced because the decoking interval increases .
- Creep and carburization rates, related to the TMT and deposit of coke, shall be minimized to the advantage economy of the production.
- a method to improve the heat transfer between a tube and the fluid flowing inside the tube itself, and in particular in the radiant coil of the steam cracking furnace, is the object of the claim No 11.
- the ERHE covered by the present invention, includes a tube heated by an external source. This tube is equipped inside with at least one body that receives energy by radiation from the enclosing tube and transfers it by convection to the process gas flowing in the annulus .
- the present invention will be more fully understood and objects other than those set forth above will become apparent when consideration is given to tbe following detailed description thereof.
- Figure 1 shows schematically a steam cracking furnace with a radiant coil equipped with various enhanced radiant heat exchangers covered by the present inventi n
- Figures 2a and 2b are front and top schematic views of one possible application of the ERHE covered by the present invention.
- Figure 3 shows schematically a different application of the ERHE covered by the present invention.
- Furnace 1 shows a firebox 2, the fLoor burners 3 and burner piping 4 for the fuel gas distribution. Inside the firebox 2 the radiant coil 5 is installed and the fluid F flows according to trie specific process requirements (heating, cracking or, in general, heat transfer) .
- the radiant coil 5 is connected to the convection bank 6. In the exchanger 6, the fluid F is preheated by hot flue gas 8 leaving the firebox by way of: the convection zone towards the stack B.
- the radiant coil 5 consists of several enhanced heat radiant exchanger apparatuses 10, arranged in series, and is designed with the appropriate surface to absorb the thermal duty required by the process gas flowing inside.
- Figures 2a and 2b show part of the ERHE according to the present invention.
- the heat exchanger apparatus 10 according to the present invention, includes a cylindrical b>ore tube 11, although different shapes of tubes and configurations of the exchanger are technically possible. Inside the tube 11 at least one body 12 is installed, which receives the radiative energy emitted by the enclosing tube 11.
- the radiant coil absorbs energy (coming from the burners, the flue gas and the refractory walls) and heats the fluid F.
- the body 12 is a cylinder equipped, at the two extremities, with one up stream ogive facing the 15 the fluid flow and the other ogive 15' on the opposite, downstream end.
- the aerodynamic profile of the two ogives reduces the pressure drop of the fluid flowing in the annulus at the inlet point and the outlet point of the tube 11.
- the reduced volume of the radiant coil leads to a reduced contact time, which allows a better selectivity (amount of high value products vs. total effluent).
- the diameter and the length of the tube 16 are calculated in order to reduce the pressure drop of the EHRE, while keeping the velocity of the fluid F in the annulus at the properly required rate .
- the energy generated in the firebox is, therefore, transferred to the fluid F more efficiently because: a)
- the surface available for the heat transfer is increased: both the tube 11 and the body 16 are active and effective. b)
- the heat transfer coefficient is improved.
- the body 16 is centered inside the tube 11 in order to have a regular cross sectional area of the annulus for a well-distributed heat flux. Such centering is carried out by means of at least one spacer 13, preferably a couple of spacers, everyone of them made of three elements disposed at 120 degrees in order to avoid irregular perturbations in the flow of the fluid.
- Body 12 should preferably have supports 14 in proximity of the downstream ending edge 15 ' .
- Inside the tube 11, several bodies 12 can moreover be installed to increase the thermal exchange throughout the entire radiant coil 5.
- Several bodies 12, covered by the present invention, can eventually be installed inside the coils of already existing furnaces.
- Figure No 3 illustrates simplified a further embodiment of the invention.
- miss ⁇ le shaped bodies 12 inside the tube 11 can be filled with metallic spheres (or metallic void cylinders) or other radiative material, having a diameter larger than half of the value of the inside diameter of the tubes.
- Such spheres 12 do not need any spacer or any other support . They are going to occupy the free spaces of all the tubes 10 and return bends 10 ' .
- the fluid F is forced to flow through the radiated particles of the tube packed with these spheres 12 ' .
- any configuration and shape of such filling elements can be used which is made of inert and radiative material able to increase the heat transfer. Provided that the pressure drop does not increase too much.
- a method for enhancing the heat transfer in process furnaces, and, in particular in the radiant coils of a steam cracking furnace, is the use of several ERHE 10 as described above in series.
